Section 460.652. Billing and credit for modified net metering customers.

(1) Net metering customers with a system capable of generating more than 20 kW qualify for modified net metering. For customers who qualify for modified net metering, a negative net metered quantity during the billing period or during each time-of-use pricing period within the billing period reflects net excess generation for which the customer is entitled to receive credit. Standby charges for modified net metering customers on an  energy rate schedule shall equal the  retail  distribution charge applied to the imputed customer usage during the billing period. The imputed customer usage is calculated as the sum of the metered on-site generation and the net of the bidirectional flow of power across the customer interconnection during the billing period. The commission shall establish standby charges for modified net metering customers on demand-based rate schedules that provide an equivalent contribution to provider system costs. Standby charges shall not be applied to customers with systems capable of generating 150 kW or less.

(2)  The credit for excess generation shall appear on the next bill. Any excess kWh not used to offset current charges shall be carried forward for use in subsequent billing periods.

(3)   A customer qualifying for modified net metering shall not have net metering credits applied to distribution charges.

(4)    If a customer leaves the provider's system or service is terminated for any reason, an electric provider or alternative electric supplier shall refund to the customer the remaining credit amount.

(5)   The credit per kWh for kWh delivered into the provider's distribution system shall be 1 of the following as determined by the commission:

(a)    The monthly average real-time locational marginal price for energy at the commercial pricing node within the electric  provider's  distribution service territory, or for a net metering customer on a time-based  rate schedule, the monthly average real- time locational marginal price for energy at the commercial pricing node within the electric  provider's  distribution service territory during the time-of-use pricing period.

(b)   The electric provider or alternative electric supplier's power supply component of the full retail rate during the billing period  or  time-of-use pricing period.
